I want to increase the video card memory. Basically I am on Windows Vista and like to play games and some photo editing work on my computer. Many a times problem arises where my computer hangs because of less memory. I quiet often get a message saying I am lacking memory and need to increase ir. So today I thought of to do the same. But I don't know how to increase the same. Can you help how to increase video memory from 128 MB to 256 MB?
